If the fireballer continues to build on his spring line -- 5 1/3 IP, 0 R, 5 K -- management may convince itself he’s the next Doc Gooden. They’ll be wrong.

Reading about Mejia making big league hitters look foolish is exciting. But before long, these guys will get wise to the dramatic natural sink his fastball has. That’s why Doc had that wicked hook when Davey Johnson took him north.

“Mejia’s slider needs a lot of work. He throws it with an inconsistent release point and arm speed, often leaving it up in the strike zone He sometimes throws his changeup too hard and doesn’t achieve enough separation from his fastball. His fastball command also can stand to improve, and even he acknowledges he doesn’t quite know where the pitch is headed when he releases it.“

A future ace? Maybe. Why risk that potential bringing him up, and subjecting him to abuse, as a one-pitch guy now?
